Pullling when cover board and tension disc can effectively prevent the cable from replacing.Also, when cable damages, user can be with
It is rapid at any time to replace, so as to not influence the use of test equipment.
The main body is provided with symmetrical through-hole.Through-hole is opened up for reducing quality itself, reduces effect of inertia.
The elastic component is spring.The locating piece is steel ball.
The belt force sensor is used for the measurement of belt force in crash tests, using with intensity Gao Ermi
Degree and small, the titanium alloy material of good mechanical property so that metal material has preferable strain effects in measurement process.
The belt force sensor is used for the measurement of belt force in crash tests, and all surfaces are all through overground
Light processing, to prevent damage dummy or bag material, while traction and frictional error is eliminated, protection is expensive on smooth surface
Crash tests dummy it is without damage.
Due to using the technology described above, the technique effect of the utility model is：The utility model overall structure is simple,
It is small, and internal part stress is rotatable, can more fully be tested.The utility model operation is easy and is not easy by sky
Between and external environment influence, locking it is firm, can compressive resistance it is big, have enough impact strengths, it is highly practical, especially meet automobile
Impact test requirement.

Specific embodiment
The utility model is described in more detail with reference to the accompanying drawings and detailed description.
The utility model structure is as follows：
A kind of rotatable belt force sensor of force rod, 1 top of main body are additionally provided with groove 6, the groove 6
For installing foil gauge, 1 side of main body is internally provided with annular buckling groove 12, and being installed with stress in the main body 1 can revolve
Rotation member, the stress rotatable part are clamped with annular buckling groove 12；
The stress rotatable part includes force rod 2, built-in rod 9, elastic component and locating piece, and the built-in rod 9 is installed
In the inside of 2 end of force rod.2 end of force rod is equipped with location hole 13, and the built-in rod 9 is equipped with U-shaped elongated slot 8, described
Elastic component is equipped between 9 end of built-in rod and force rod 2.Spring 10 is connect or in built-in rod by clamping with built-in rod
Tail portion is equipped with 10 open ended limiting cavity of spring, is placed in for spring 10.
The locating piece 13 is set in U-shaped elongated slot 8 and is adapted with location hole 13, is adapted and refers to, locating piece diameter omits
It more than location hole 13, finally withstands on location hole 13, exposes 13 part of location hole and be stuck in annular buckling groove 12.The locating piece
It is arranged in annular buckling groove 12.
The elastic component is spring 10.The locating piece is steel ball 11.
1 side of main body is equipped with the cover board for being connected with detection device, and the cover board includes inside cover plate 3 and outside
